Scripts works under CGI but not under mod_perl

["Manoj Bist" <suppressed>]

Hi,

I created a perl binding for a third party
"C "library using swig. This works fine under CGI but consistently
fails under mod_perl.
Is there a known set of calls(mulithreading etc.) that is not expected to work under mod_perl?

I have gone through almost all the mod_perl caveats that I could google. I have been struggling with this for quite some time.
I would really appreciate any insights/pointers/ideas on troubleshooting this.

Thanks,

Manoj.
